MTF Compensation

MTF Compensation reduces the impact of the chart material on measured imaging system MTF. This compensation greatly increases the resolution suitability of test charts, enabling one to test with a lower precision chart or to accurately test at a closer distance where uncorrected MTF results would be degraded.

Geometric Calibration

Imatest produces a geometric calibration from a projective camera model and images of checkerboard patterns. A geometrically calibrated device provides a mapping between pixel coordinates and real-world position, e.g., for stereo imaging depth perception.
